As discussed, we may want to support metrics creation via netobserv for the observability events. For example, netobserv can create a metric that reports all network policy traffic denial labelled by namespace / pod etc.
Considering the current tech preview implementation, this would require changing the API interface between netobserv and ovnk-observe.

old kernel/OVS/ovn-kubernetes + new netobserv => netobserv can detect if it's running on older ocp version and warn when the users try to enable the feature.
OVN Observability is a feature that provides visibility for ovn-kubernetes-managed network by using sampling mechanism.
That means, that network packets generate samples with user-friendly description to give more information about what and why is happening in the network.
In openshift, this feature is integrated with the Network Observability Operator.
The purpose of this enhancement is to define an API to configure OVN observability in an openshift cluster.
